2020 Mercedes-benz G550 problems
The Mercedes-Benz G-Class, colloquially known as the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military off-roader, later more luxurious models were added to the line. In certain markets, it was sold under the Puch name as Puch G until 2000.
The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature.
Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of 44 years. Only the Unimog surpasses it. In 2018, Mercedes-Benz introduced the second-generation W463 with heavily revised chassis, powertrain, body, and interior. In 2023, Mercedes-Benz announced plans to launch a smaller version of the G-Class, named "little G"—though no definitive date was given for the launch.
The 400,000th unit was built on 4 December 2020.
The success of second-generation W463 led to the 500,000th unit milestone three years later in April 2023. The 500,000th model was a special one-off model with agave green paintwork, black front end, and amber turn signal indicators in tribute to the iconic 1979 press release photo of jumping W460 240 GD.

Common 2020 Mercedes-benz G550 problems
The Mercedes-Benz G550 2020 is a luxury SUV known for its off-road capabilities and high-end features. However, as with any vehicle, there are common problems that owners have reported.
One issue that has been reported by owners is the vehicle suddenly shutting down while driving.
Another issue that has been reported is related to the electrical system. Approximately 6,500 model-year 2019-20 Mercedes-Benz G550 4Matic and G63 AMG 4Matic vehicles are being recalled due to the electrical resistors in the differential locking modules potentially malfunctioning. If this occurs, the antilock brake system and the electronic stability program may be deactivated, increasing the risk of a crash. Mercedes-Benz will begin notifying owners on April 14, and dealers will inspect and replace the differential locking modules as necessary.
The 2020 Mercedes-Benz G550 has also been subject to two minor recalls. The first recall affects just shy of 1,700 GLB250 SUVs from the 2020 model year, and is related to an incorrect voltage converter that may have been installed in the second-row accessory power outlet.
In addition to these specific issues, the Mercedes-Benz G550 is known to have some common problems that are reported to RepairPal. These include door lock and window switch failure, oil level sensor or crankshaft position sensor failure, and brake light switch failures. The door lock, door handle, and window regulator problem is exactly what it sounds like, with components failing and leaving a window stuck down or a door that can only be opened from the inside. This issue has been reported by 34 owners of G 500s from 2002 through 2008, with an average mileage of 97,028, and by 15 owners of G 55 AMG SUVs from 2003 through 2010, with an average mileage of 89,800. The average repair cost for this issue is $110-$139.
Brake light switch failures have been reported by 13 owners of Mercedes G500 SUVs, from the 2002 through 2008 model year, and by eight owners of 2003-2010 G55 AMGs. This issue can cause the brake lights to fail to illuminate when the brakes are applied, which can increase the risk of a collision. The average repair cost for this issue is $100-$150.
Oil level sensor or crankshaft position sensor failure sensors have also been reported by owners of both regular G-Class SUVs and G Wagon tuned by AMG. These sensors can fail and cause the engine to leak oil or not start at all. The crankshaft position sensor is used by the engine control module to determine the exact position of the crankshaft, and if it fails, the engine will not start. The oil level sensor can fail and cause a trickle of oil to leak out and even burn up on the hot engine, causing a steady cloud of obnoxious smoke. The average repair cost for these issues is $100-$200.
In conclusion, while the Mercedes-Benz G550 2020 is a luxury SUV known for its off-road capabilities and high-end features, there are common problems that owners have reported. These include the vehicle suddenly shutting down while driving, electrical system issues, and problems with the door locks, windows, and sensors. It is important for owners to be aware of these issues and to have their vehicles inspected and repaired as necessary to ensure safe and reliable operation.
